To what accuracy does the system accept a decimal OK answer?

Hi, I recently solved this problem within 5% error . It is marked wrong! Please tell the minimum demanded accuracy.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Our tolerance is set at 2% by default for floating point answers.

To be particular in that problem, we also require the composition of air. I assumed it to be $N_{2}$ and $O_{2}$ in 4:1 ratio. The person should also give the values like $g$ , $R$ and temperature . So, the error was due to my own assumptions.

I will tell yoy a funny thing. There was once a question in which the probability was asked, you know it will be 0.something. In the answer box, it was written 'decimals OK', so I simply wrote 0 as the answer. I don't know why, but it went wrong!
